17 Claims.

This invention relates to a surface decorating machine, and more particularly to a machine for applying a decorative design or tracery to surfaces to be decorated. Machines of this nature are sometimes used to apply a decorative design or coating which simulates natural wood grains, marble, etc., to the surface of other materials, which are more desirable than those being simulated, either because they are less, expensive, or because they are more easily adapted for use in the production of articles of manufacture.

The present invention is especially concerned with a decorating machine for decorating the surfaces of workpieces which are difficult to handle, because of their size, weight or shape. The present invention is also concerned with an improved decorating machine, in which comparatively large, and therefore heavy printing roll is used; such machine being arranged to facilitate adjustment of the roll to regulate the printing pressure, without disturbing the workholder, the workholder support, the pattern or the inking mechanism, These, therefore, are the general objects of the present invention.

Another object of this invention is to provide an improved support for a decorating unit, to facilitate the decoration of large or cumbersome workpieces.

A further object of the present invention is to provide an improved control mechanism for a surface decorating or graining machine.

Another object of this invention is to provide a decorating machine with an improved work support to facilitate travel of the work relative to the decorating unit, together with a decorating unit so arranged as to enable work to be positioned on and removed from a reciprocating carriage from the same side or opposite sides of the machine, as desired.

Another object of this invention is to provide a decorating machine which will be especially adaptable for decorating workpieces of varying thicknesses.

Another object of this invention is to provide a decorating machine which will receive a workholder and progress such workholder through the machine, automatically stopping the movement of the workholder when the work has been decorated.

Other objects of this invention will become apparent from the following description, reference being had to a preferred embodiment of the invention illustrated in the accompanying drawings. The essential novel features of the invention will be summarized in the claims.

In the drawings, Fig. 1 is a side elevation of our improved decorating machine; Fig. 2 is a fragmentary plan view, illustrating the workholder and its supporting mechanism; Fig. 3 is an enlarged plan view of the machine, certain parts being broken away to-more clearly illustrate the driving mechanism; Fig. 4 is a vertical section, taken in the plane indicated by the line 4 on Fig. 3; Fig. '5 is a sectional View, indicated by the line 5-5 of Fig. 4, the view, however, being swung through a clockwise angle of 90 degrees to facilitate illustration; Fig. 6 is a fragmentary Vertical section, the plane of the section being indicated by the line '65 on Fig. 3; Fig. 7 is a section similar to Fig. 6, but illustrating the decorating unit in a different position; Figs. 8 to 12,

inclusive, are electrical diagrams, illustrating an electrical control mechanism for use with the 0 decorating machine.

Our improved decorating machine comprises a framelfl, in which a decorating unit I2 is mounted for swinging movement about a horizontal axis above the workholder M, which is reciprocated on fixed guiderails It, by a motor "3.

The frame It comprises a base 20, having upstanding side frame members 2! and 22 at opposite sides thereof. At their upper ends, the side frames are joined by a cross-frame member, such as the shaft 23.

The decorating unit l2, mounted in the base frame H], for swinging movement about a horizontal axis. The decorating unit is mounted in a supplemental frame, which comprises a pain of frame plates 25 and Z6, journalled at their upper ends on the main frame shaft 23 and joined together by suitable cross-frame members 21. The supplemental frame is positioned axially of the shaft 23, by collars 24, which are secured to the shaft, and is positioned radially of the shaft by plungers or jacks I50, carried by the base 29, and hereinafter to be more fully described.

The decorating unit, mounted on the supplemental frame, comprises a pattern 3! an offset or transfer roll 3!, doctor blades 32 and 33, for the pattern and transfer rolls, respectively, and an ink applicator for the pattern. The pattern extends about the periphery of a pattern roll 34, which is supported by a shaft 35, journalled in the supplemental frame plates 25 and 2G.

The pattern 39 is preferably a photo-engraved 'intaglio printing plate, and is supplied with ink by an inking roller 36, which is secured to a shaft 31'. This shaft is journalled in a pair of arms 38,

which, in turn, are journalled on pins 39, carried by respective brackets MI. These brackets are secured to the cross-frame member 2'! by bolts 4I. Adjusting screws 2, carried by respective arms 38, engage the brackets ll! to swing the arms 38 together with the inking roller about the axis of the pins 39. This aligns the inking roller with the pattern and adjusts the pressure between such roller and the pattern, thereby regulating the amount of ink applied to the pattern.

The inking roller is rotated, as will be hereinafter more fully described, and has its lower portion submerged in a graining paste or ink, carried in a reservoir 43, which is secured to the brackets 4 I heretofore described.

Any surplus ink applied to the pattern 35 by the inking roller 36 is removed by doctor blade 32. This doctor blade is mounted on a bar A5, journalled in a pair of brackets 45 carried by respective frame plates 25 and 26. The doctor blade may be reciprocated axially relative to the pattern by any well known means, not shown, and is resiliently pressed into engagement with the pattern in the usual manner. I

The inked pattern is transferred from the pattern to the transfer roll 3i, which is provided with a coating M of transfer material, such as the usual glue and glycerin compound. However, in some instances a rubber composition is used. The transfer roll is secured to a shaft 48, journalled in arms 49. The arms or bearings 49 are pivotally mounted on pins 55, carried by the frame plates 25 and 26.

To position the transfer roll, relative to the pattern roll, the bearings 49 are extended outwardly through openings 5| in respective frame plates 25 and 25, and are each positioned relative to such plates by a set of adjustable pins or plungers.

One set of these pins is best illustrated in Fig. 4, and as there shown, comprises a pin 53 threadingly mounted in a boss 54 of its respective frame plates 25 or 26, and engage one end of its respective bearing 59. The other pin of the set comprises a plunger 55, which engages the opposite end of the bearing, and is slidably mounted in a bracket 56 secured to the frame plates 25 and 26, as' the case may be. Adjustably carried by the plunger 55 is a member5'l, which is arranged to be engaged by a cam 59, mounted on a shaft, and which, when the mechanism is in use, is in the position shown in Fig. 4. As there shown, the cam 59 maintains the plunger 55 inwardly, causing its bearing to be gripped between the two pins 55 and 53.

When the graining mechanism is stopped, a handle or lever BI is swung in a clockwise direction to release the transfer roll. This lever is -mounted on a shaft 52, journalled in the frame plates 25 and 25. Drivingly connected with this shaft is a pair of gears 63, which mesh with respective gears B l on the cam shafts, thus causing the cams to be moved, drawing the respective plungers 55 away from the bearing 55, permitting the roll to swing in a counter-clockwise direction through the influence of gravity.

The ink remaining on the roll 3I, after the image has been transferred to the work, is removed by the doctor blade 33. This doctor blade is secured to a shaft 65, supported in suitable bearings 56, carried by respective frame plates 25 and 26. The doctor blade 33is resiliently maintained in contact with the roll 3I, in the usual manner.

The driving mechanism for the various rolls is best shown in Figs. 1, 3 and 4. As there shown,

the motor I 8 is connected by a suitable driving belt 65, with a pulley 66, secured to the driven shaft of a speed reduction unit 68. The driving shaft 69 of the change-speed unit 68 carries a sprocket wheel III, which is drivingly connected by a driving chain II, with a sprocket wheel I2, secured to a shaft '13, journalled in bearings 14 carried by the base 25. The shaft'l3 extends outwardly through an opening in the frame plate I0. Secured to the outer end of this shaft is a bevelled gear 15, which meshes with a similar bevelled gear 15, carried by a vertically extending shaft ll journalled inbearings I8 carried by the main frame plate It. The shaft i8 is connected by a universal coupling 19, with a shaft 80, which, in turn, in connected by splines M, with another shaft 82. The shaft 82 is connected by a universal coupling 83, with a vertically extending shaft 84, journalled in a bearing bracket 84, which is supported by and journalled on the pattern roll shaft 35, heretofore described. Adjacent its upper end, the shaft 84 carries a bevelled pinion 87, which meshes with a bevelled pinion 88, drivingly secured to the pattern roll shaft, thereby driving the pattern roll.

The offset and transfer roll is driven from the pattern roll shaft 35. As shown in Fig. 4, a sprocket wheel 90 is drivingly secured to the shaft 35, and is drivingly connected by a driving chain 9! with a sprocket wheel 92, rotatably mounted on one of the pins 50, heretofore described. Drivingly connected to the sprocket wheel 92, and mounted on the same pin 50, is a gear 93, which meshes with a gear 94, drivingly secured to the transfer roll shaft 48. An adjustably mounted idler sprocket 95 engages the chain 9| to maintain the proper tension thereon.

tern roll shaft 35. As shown in Fig. 3, a sprocket 97 is secured to the far end of the shaft 35, and is connected by a driving chain 98, with a sprocket 99, carried by a stub shaft, journalled in a supplemental frame bracket Hill. The sprocket 99 carries a gear IQI, which constantly meshes with a gear I52, carried by a stub shaft I03, journalled in the supplemental frame. The gear I02 is provided with an axially extending pin I54, to engage a radially extending pin I05, carried by the ink roller shaft 31, thus providing a driving connection between the driving mechanism and the inking roller shaft, which readily permits removal of the inking roller.

As heretofore mentioned, the work is supported on a carriage I4, which is reciprocally mounted on guiderails I6. As shown in Figs. 1 and 2, the guiderails it pass between the decorating unit and the base 20 of the machine; These rails may comprise comparatively rigid, tubular members, and are supported by standards II 0, carried by the base of the machine, or the machine supporting surface.

The carriage I4 comprises a rectangular frame, having longitudinal and transverse frame members I I I, reinforced at the corners by gussets I I2. Mounted on this frame and extending downranged to permit a workholder H9 to be rolled.

onto the carriage. The workholder, as shown in wardly therefrom is a series of brackets H4, in

Figs. 1 and 4, may be fixed against movement relative to the carriage, by a plunger I20, slidably mounted in a bracket I2I carried by the carriage I4, and are arranged to be moved upwardly to engage an opening in a workholder bracket I22 by a cam I23. The cam is carried by the bracket I2I, and is provided with an operating lever I24. A spring I25, interposed between the pin I25 and the bracket I2I, serves to maintain the pin in engagement with the cam.

The carriage I4 is reciprocated by the motor I8. As shown in the drawings, and especially Fig. 3, the driven shaft of the speed-reducing unit 68 is provided with a sprocket wheel I25, which is drivingly connected by a chain I 26, with a sprocket wheel I21, secured to a jack shaft I28 mounted in bearings I29, carried by the base 20. Splined to the shaft I 28 is a clutch sleeve I35. This clutch may be moved axially of the shaft to selectively coact with and drive either gear of a pair of gears I3I and I32, which are rotatably mounted on the shaft.

When the clutch is in the position shown in Fig. 3, the carriage travels in the direction of the arrow there shown. As illustrated, the clutch I30 drivingly connects the gear I3I with the shaft I28. The gear I3I meshes with an idler gear I33, which, in turn, meshes with a gear I34, drivingly secured to a drive shaft I35, mounted in bearings I36, carried by the base 20. Also secured to the shaft I is a sprocket wheel I31, which constantly meshes with a sprocket chain I38, secured to the underside of the carriage I4, as indicated in Fig. 4.

When the carriage has travelled in the direction of the arrows in Figs. 1 and 3, a distance such that the work carried by the workholder II9 has, to the left, passed beyond the transfer roll 3|, an arm I30 secured to the right-hand end of the carriage IIS, engages one arm I of a bell crank I36, which is pivotally mounted, as at I4I on the frame I0. Theother arm I42 of this bell crank is connected by a link I43, with a slide I44, which carries an upstanding bracket I45, provided with pins I46, to engage an annular groove I41, in the clutch I30.

The carriage, in its travel towards the left,

Figs. 1 and 3, swings the bell crank I40, I42 in a I counterclockwise direction, causing the clutch to be shifted from the position shown in Fig. 3 into engagement with the gear I32. This gear meshes directly with a gear I48, which is drivingly secured to the shaft I35, thus reversing the direction of rotation of the sprocket wheel and causing the carriage to move toward the right. When the carriage has moved to the extreme right-hand position, another lever I49, depending from the carriage, as shown in Figs. 1 and 4, engages the bell crank and restores the parts to the position shown in Fig. 3, thus again reversing the driving connection to the carriage.

When a glue and glycerine compound or similar transfer material is used on the transfer roll, it is desirable to limit the printing pressurethat is, the pressure between the transfer roll 32 and the work carried by the workholder H0. This pressure is adjusted by swinging or rocking the decorating unit about the axis of the shaft 23 of the main frame. It Will be noted from Figs. 3 and 4 that the offset roll lies to the left of a vertical plane, passing through the pivot axis, namely, the axis of the shaft 23. Thus, the printing unit swings, under the influence of gravity, into contact with the work. This swinging movement is limited by a pair of plungers or jacks I50,

the frame plates 2I and 22.

which are mounted in main frame brackets I5I for vertical movement. These plungers engage respective rollers I53, which are carried by stub shafts I54, secured to the respective supplemental frame members 25 and 26. The lower end of each plunger I50 is guided by a bearing I51 carried by the base 20.

Rotation of the plungers or jacks I50 is prevented by pins or bolt- I58 (Fig. 4), which extend through the respective bearings I5I and engage slots I59 (Fig. 4) formed in the plungers in the usual manner. To manually raise or lower the plunger, and thus adjust the position of the decorating unit relative to the work, we provide a hand-wheel I53 (Figs. 1 and 3). This handwheel is secured to a shaft I-6I, journalled in the frame plate 2|. Secured to the shaft I6I is a sprocket wheel (not shown), but which is drivingly connected by a chain I62, with a sprocket Wheel I63, secured to a shaft I64 journalled in Secured to this shaft is a pair of gears I65, which mesh respectively with gears I66, carried by shafts I61, which are journalled in respective bearing members I51, heretofore mentioned. Drivingly secured to each shaft I61 is a bevelled pinion I68, arranged to constantly mesh with a bevelled pinion I66, which threadingly engages its respective plunger I50. Thus, when the hand-wheel is operated, the

plungers are raised or lowered, consequently moving the transfer roll towards or from the workpiece, thus limiting the printing pressure. It is apparent that after the carriage has moved to the extreme left-hand position, the hand-wheel may be operated to swing the decorating unit in a clockwise direction about the shaft 23, thus raising the transfer roll above the decorating plane to permit the carriage and the workholder II8 to move toward the right, without danger of contact between the transfer roll and the decorated workpiece.

To enable the position of the transfer roll to be adjusted to individual workpieces, which may vary in height, thus varying the decorating plane and still maintain the proper printing pressure, we have secured to one of the plungers I50, as indicated in Fig. 4, a bracket I10, carrying an arm I1 I on which an indicator I12 is pivotally mounted. The decorating unit is moved so that the lowest surface of the transfer roll is in the same horizontal plane as the surface to be decorated, whereupon the printing pressure will be the same, regardless of the vertical position of the surface to be decorated. It will be noted that the arm I15 is adjustably positioned on the plunger I50, to the end that the pressure may be adjusted for climatic or other variable conditions, other than the height of the work surface rotation to the guide-rails I6.

As heretofore mentioned, the decorating machine with which this invention is concerned, is especially adapted for the decoration of a workpiece which varies in thickness, such as is indicated by the dotted line WI in Fig. 1. When such workpieces are to be decorated, a transfer roll, having a rubber composition surface coating is generally used, as with such a coating the printing pressure may be much greater than when a glue and glycerine compound is used. The plungers 550 are then adjusted to permit decoration of the lowest point of the surface to be decorated. The workpiece will then swing the unit according to the thickness of the workpiece.

When the irregularities are the same in all workpieces, as sometimes is the case, a glue and glycerine composition transfer roll is preferably used, as better results may be obtained thereby. In such instances, a pair of rollers or discs, one of which is indicated by the dotted lines 2'15 in Fig. 3, are secured to opposite ends of the oifset roll. These discs coact with fixed cam rails 216, carried at opposite sides of. the workholder, to positively raise and lower the decorating unit. The surface contour of the cam rails is substantially identical with the surface contour of the workhence a predetermined printing pressure may be maintained.

When the machine is used continuously on similar workpieces, that is, workpieces which are all of. the same thickness or which are so mounted on their workholders that the surfaces to be decorated are the same distance above the carriage Hi, we may provide an automatically controlled drive for the carriage and for swingingthe decorating unit about its axis to raise and lower the transfer roll, and thus permit the work, after being decorated, to be returned to the right-hand side of the machine (Fig. 4), without disturbing the freshly inked impression.

The automatically controlled drive includes a motor 250 for reciprocating the carriage and a second motor 200. The motor 200' may be connected to the plunger drive shaft I64, in any well known manner, as, for instance, by a gear reduction unit similar to that shown at 68 in Fig. i, but having its driven shaft drivingly connected with the shaft I04.

When the automatic control is used, both the motor 250 and the motor 200 are reversing type motors and the clutch mechanism, heretofore described in connection with Fig. 3, is eliminated. A gear reduction unit (not shown) is drivingly connected between the motor 250 and the carriage sprocket wheel .drive shaft I35. The motor l8 then functions only to drive the decorating rolls. The motors 250 and 200 are controlled by electric circuits and switches illustrated in Figs. 8 to 12, inclusive, and including a pair of reversing switches 20! and 202, respectively. The switch 20! controls the carriage motor, and is operated by the carriage bars I39 and M9 which, when the clutch mechanism is used, control such clutch as heretofore described. The switch 202 controls the jack operating motor 202 and is actuated by the movement of the plungers, the arm of such switch being arranged. to be engaged by the arm I'll, which, as heretofore described, is carried by one of the jacks I50.

Each of the switches 20! and 2G2 are of the reversing type-that is, they are arranged to control their respective motors, so as to reverse the direction of rotation of the motors. The circuit to each motor. however, is made through the switch of the other motor, so that while the respective motor switches control the direction of rotation of their respective motors, the flow of current to each motor is controlled by the other switch for the other motor.

The circuits are best illustrated in Figs. 8 to 12. As there shown, Fig. 8 illustrates the circuits when the carriage is at rest in the right-hand or loading position. When the carriage is loaded, a manual switch member 204, associated with the switch 202, as will hereinafter be more fully described, is manually moved from the position shown in Fig. 8 to the position shown in Fig. 9. This causes a circuit through the motor i 8 to be made. As shown in Fig. 9, this circuit is made from the main line 2 l 0 through a line 2| i, to one member 2l2 of the switch 204. From there,

through lines 2I3 to the motor, and. thence through a line 2 i 4, to another switch member 2 I of the switch 20!, thence through a line 2|6a, to the manually operable switch 204, heretofore described, which is connected by a line 2l6, with the other main line 2H. The field of the motor 2% is connected between the line 2 and a line 2 [8, which is connected to the main line Zn. In this instance, the direction of the carriage-moving motor is indicated by the arrow and is such as to cause the carriage to travel toward the left, thus performing the decorating operation.

As the carriage reaches the extreme left-hand position, the arm I39 thereof moves the switch arm of the switch 20'! from the position shown in Fig. 9, to the position shown in Fig. 10. This switch connects the line 2 with the switch member 2i5, thence through the line 214 to the motor 250, and from thence through the line 2 l3, the switch member 2I2 and a line 220 with a switch point 22! of the switch 202. however, is in such a position that the switch point 22! is open. Thus, the circuit to the motor 250 is cut. However, as when the switch member 20! was shifted to the position shown in Fig. 10, the lines 2 i1 and 258 were connected by a switch member 222 of the switch 20!, with a line 223, and a switch member 224 of the switch 202, with a line 225, leading to the motor 200, and thence through a line 226, a switch member 221, of the switch 202, with the line 223, which is connected with a main line 2i0, thus energizing the motor 200 to rotate in the direction of the arrow shown in Fig. 10, causing the jacks or plungers to be raised.

When the plungers have been raised a predetermined distance, sufficient to cause the transfer roll to clear the work, they actuate the switch member 202 to move the switch member 202 from the position shown in Figs. 8, 9 and 10, to the position shown in Fig. 11, in which position the manual switch member 204 has been moved by the switch 202 to contact with the contact point 22!, thus energizing the'circuit to the motor 250, and causing it to operate in a reverse direction, as indicated by the arrow in Fig. 11, returning the carriage to an extreme right-hand position.

The movement of the switch member 202, above mentioned, from the position shown in Fig. 10 to the position shown in Fig. 11, operates the switch members 224 and 221 of the switch 202 to reverse the flow of current through the motor 200. However, the switch member 221,

under such reversing condition, is connected with a switch point 230, which, in turn, is connected with a switch point 23! of the switch 20I, which at this time is not engaged by any switch member of the switch 20L Therefore, the circuit to the motor 200 is open, and thus the movement of the lifting jack is stopped.

When the carriage reaches the extreme righthand position, the switch 20! is moved, by the depending arm 549 of the carriage, from the position shown in Fig. 11 to the position shown in Fig. 12. This causes the switch member 222 to engage the switchpoint 21, thus coupling the motor 203 with the line 2l8, and thus with the power line 2 l1, thereby energizing the motor 200, causing it to rotate in the direction of the arrow in Fig. 12, thus lowering the jack and permitting the decorating unit to return to its normal or decorating position.

When the jacks have been lowered a predetermined distance, the arm IH thereof contacts the switch member 202,.moving it from the position This switch,

. in the drawings.

shown'in Fig. 12 to the position shown in Fig. 8. This reverses the direction of the flow of current through the motor 200, but inasmuch as the switch member 221, through which current must pass in order to energize the motor 200, is connected by a line 240, with a switchpoint 24! of the switch 20], which point is not contacted by any member of such switch, the circuit to the motor 200 is opened.

The connection between the switch 202 and the member 204 is a lost motion connection, so that as the switch moves from the position shown in Fig. 12 to the position shown in Fig. 8, the switch member 204 is not moved a distance sufficient to cause it to contact with the line 2I6, thus the circuit to the carriage motor remains opened until the switch 204 is manually operated. This per-- mits the removal of a decorated piece from the carriage and the positioning of an undecorated piece thereon, whereupon the switch 204 may be manually operated and the cycle of operation again renewed.

When the work-is placed on the carriage on one side of the machine, for example, on the righthand side and moved to the left-hand side to'be decorated, and removed from the workholder at the left-hand side of the machine, it may be desirable to cause a dwell of the carriage before its direction of movement is reversed. If this is desired, the switch-point 221, shown in Figs. 8 and 9, may be moved to the position shown by the dotted line 22Ia (Fig. 11), whereupon the movement of the switch arm 202, due to the lost motion connection between it and the arm 204, will move the switch-point 204 to the position shown Inasmuch as the switch-point 22I has been moved, no circuit will. be made until the switch member 204 is manually moved into contact with the switch-point 22m.

Obviously, both the" switch members 20| and 202 are of the type generally known as snap switchesthat is, they are actuated, for instance, by a dead-center spring, so that they will not move from the contact in one position until the spring has been sufiiciently compressed to carry them to their other contacting position, regardless of the'fact that motion of either the jack or the carriage is entirely stopped when .one contact is broken.

From the foregoing discription, it will be seen that we have provided a simple and efficient decorating machine, especially adapted for the decoration of large and/or cumbersome articles of manufacture, which mechanism is readily adjustable to regulate the printing pressure, and

wherein work may be positioned on the machineand removed from the mechanism at the same side of the machine, and wherein the mechanism is so controlled that the action of the work carriage from the time the work is positioned thereon until the work is returned in a discharged position, is entirely automatic.
